EYELETlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 760,617, dated May 24, 1904. Application filed September 19, 190 3, Serial No. 173,817. (No model.) i

- Be it known that I, ABEDNEGO DEwEs,a citizen of the United States, and a residentof 'NewYork, county and State of New York, have "invented Improvements in Eyeleting-, Machines, of whichthe followingis a specification. I d v The improvements in eyeleting machines forming the sub ect of this invention embrace in .one machine a means for puncturing or; formlng the holes 1nv the materlal to be eyeleted for the reception of the eyelets, means for applying the'eyelet to the hole so formed, and means for moving the material after being punctured to vbring the puncture or, hole formed. therein into position to receive the eyelet, the puncturing andeyeleting means' being stationary and preferably'arranged side by side."

let-applying device whereby both the eyelet feeding and upsetting mandrels are'moved to- .Ward'the material, so that theeyelets will be clenched thereon without disturbing the material, and improved operating devices foractuating the puncturing, the eyeleting, and the material-carrying. means whereby they act in unison and perform theirifunctions during one complete operation or revolution of the machine. f 5 These improvements, with others relating Fig. 5 shows a portion of the automatic clutch}, of the'machine. The material or article to be eyeleted, which will generally be in sheet form, is placed upon the table a and held thereon by theholdin'g guides a and a having spring-clamps and secured adjustably onthe table by slot and clampingscrew and nut connections and which are suitably set to retain the material or articlelin" proper position to be acted upon machine.

by the-puncturing or punching 'device'when the table is in itsnorm'al position. These spring-clamps are shown as extensions of a projecting from the'faces of the adjustable parts a a. This table a isadapted to slide or move laterally, and to enable it to be moved with freedom itis preferably carried by par allel links or arms 6]), which are pivotally connected to theunde'r side of the table at their upper ends and are connected to shafts I) and'b having bearings on the bed 0 of the The shaft 6 extends to the rear of the machine and is thereprovid ed with arm 01,

upon by the fa'ce' cam e, secured to the ,main shaft f, which is fitted to rotate in bearings located at the rear of the bed 0. The tablecontrolling device-is provided with means by 7 i which the table may be set and held. in its ini-' It also includes improvements in the eyetial position, here shown as consisting of an arm g, securedto the shaft Z2 and having a set-screw g passing through its end and arranged to bear on the bed a, and a spring 9 connected between a moving part of the tablecontrolling device and a'fixed point o'nthe machine, arranged to bring the table into its normal or initial position after having been moved by the cam va.

construction. Its body or main portion and the V body or mainportion e' of the eyeleting device to special features of construction, will now befully described, reference being had to the are for convenience and cheapnessi of manu 'facture combined in one castlng- 1n the form' 1 of a standard 7', which is rigidly secured to the bed'c. The punch [L is aotuated by the lever A, which has a link if connected at its rear end. This link extends downwardly, and its lower part is slotted, so asto embrace, be conlo'wer or eyelet-feeding mandrel d of the eye- 3 leting'device'is actuated by the lever 'z",which is pivoted to the standard 7" at f aud has a pendent link i also fitted to slide on the shaft reservoir 7," to'the eyelet setting device.

Ibov

7' and the side lever f pivoted at j to the side of the standard and having its outer end working in a slot or groove in the mandrel j,

. the link 7' being connected to the inner end of the lever f and to the lever Z, as shown at Fig. 1, the arrangement being such that as the eyelet-feeding mandrel Z rises after taking an eyelet from the chute of the eyelet-box and passes the eyelet through the hole made in the material the upsetting-mandrel j is caused to descend, and the eyelet is clenched between the two mandrels onto the material while it rests normally on the table a.

, On the shaft f is fitted two face-cams k and Z, between which the two links [L2 and i play. Both of these cams are fitted to rotate positively with the shaft f, but are adapted to be set on said shaft in two positions for the purpose hereinafter described, which may be accomplished by the feather f and slot connections and set-screws f (Shown in the drawings.) The camhas a cam-groove is in its face adjacent to the link if and into which extends the roller m on the link 76 when the cam is set to operate the punching device it, and the cam Z has a cam-groove Zin its face adjacent to the link "J of the eyeleting device and into which extends the roller a on the link 2' when the cam is set to operatethe eyeleting device. The links 71, and i are also provided with rollers'o and p, fitted on bracket extensions 0 and p of the links if and 2' These rollers 0 and p are adapted to roll in circular grooves k and Z of the cams 7c and Z, respectively, but are just clear of the cams when said cams are set to operate both the punching and eyeleting devices, as shown at Fig. 3.

The machine, as before stated, performs one complete operationthat is, the punching device is first operated, then the table is 'moved, and then the eyeleting device is operat1ngfor one complete movement or revolution of the machine, and to cause such action it is advisableto use an automatic stop device, which may be of any of the usual forms. A suitable device for such purpose is here shown consisting of a pulley g, which will be continuously driven, a sliding clutch member 1 on its hub, a clutch member 8, se-

causing a disengagement of the clutch and a stoppage of the machine.

As before stated, this machine is designed to be used as an individual punching-machine and as an individual eyeletingmachine as well as a compound punching and eyeleting machine. If it is desired to perform punching operations only, the cam Z is slid on the shaft f until the roller enters the circular groove Z and the roller a leaves the groove Z, said rollers being so arranged that before the roller it leaves the cam the roller p will be engaged, so that the eyelet mechanism is always controlled and the eyeleting-mandrcls are held in inoperative positions when the machine is used for punching purposes only. If eyeleting operations only are to be conducted, then the cam 7 is slid on the shaft f to change it from its operating to its locking roller in the same manner as the cam Z is changed. Under both of these modes of operation it is desirable that the table a be held stationary. This may be accomplished by screwing the 'setscrew 9 suflici ently far through the controlling-arm g to set the roller cZ away from the cam 0 out of the range of action'of said cam.

I claim as my invention- 1. In an eyeleting-machine, the combination with a puncturing device and an eyeleting device, arranged side by side and permanently located, of a table forming the sole support for the material to be eyelcted and provided with adjustable holding devices adapted to hold and locate the material to be operated upon; and means for moving the table so as to bring the hole produced by the puncturing device into the field of action of the eyeleting device.
